I have a customer that has an 871W ISR. They are using WEP encryption and a mix of b and g cards. Recently they have started losing connection to all of their wired network resources and the wan, but they don't lose association with the 871W itself. They show excellent signal strangth and keep their IPs. A reboot of the router immediately fixes the problem. There seems to be no pattern or common event that triggers any of this. Anyone else seen this problem before? It started happening after I did a sh tech and the router locked up halfway through it, so I had to reboot. I've reloaded the image thinking that may fix the problem and it has not.
